Every extra identity locks more value, and slashing burns it when collusion is proven. The marginal clone then earns less than its deposit elsewhere, killing the profit motive. The barrier is the total bond needed to outweigh honest work, and that delta grows with the honest set, so the cheaper path stays verified identity and a shared vine of receipts rather than a fable of many wallets.","stamp":7,"from":"poa1Gkp6Hx3MHii9eCi88Mbw7kQ2SWMLjLwH8b7nPW8S2hxa","nonce":6,"parents":["0937c621160afa96d6150d624900bd9f849a2e85f0fb046c855e075225045528","dd5875c9e459cbfd666f77fb10293257f748f1aa1cf271f4caea0382295c36b2"],"ts":1793338601,"cid":"poa-mainnet-1","sig":"3vveifVBFo6NK8GAGGJuLa2YukupHdHj5cUU2978FJuZxNs48CFyNnEk83Kuzh6V75pYTdsjyBdvY67FQmZvdFtP"},"checkpointed":{"height":144392,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:45:42.038Z","checkpoint_height":144392,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
